Overview
Unzipping in different spots vents heat, or the bag opens flat as a quilt on warm nights, thanks to the Free Flow zip system. High loft goose down treated against moisture fills box baffles in a relaxed mummy cut.
Venting and quilt options extend its range across three seasons, and the cut gives room to move. Packed size and comfort limits are missing, which matters for backpacking.
Who it's for
Three season backpackers and couples who zip bags together suit it. Taller sleepers, or winter campers, need a longer or warmer bag.
Pros and cons
- High fill power down
- Water resistant down treatment
- Opens flat as a quilt
- Wearable around camp
- Temperature unit not stated
- Packed size not listed
- Not for sleepers over six feet
- Occupancy spec listed incorrectly
Performance notes
Box baffles hold down in place so it stays lofted over the torso. The dry treatment helps down hold warmth in damp air. Opening zips at the sides or foot dumps excess heat.
